    Clear Gel test - Federal 9mm +P 124 Grain HST

    Thanks for sharing this. The 124gr +P HST is the current load for my Glock so it's always good to see additional validation of its performance.

    I don't carry a 9mm, but appreciate the testing. Never heard of a Boberg, have they been around long?

    I think they started shipping around September 2011.

    Ljutic,

    You list the maximum expansion of this round as being 0.661".

    Do you happen to know what the average of the maximum and minimum expansion measurements is?

    Clear Gel test - Federal 9mm +P 124 Grain HST

    there's a difference between maximum expansion and final expansion. in order for a bullet to begin to lay down upon itself, it has to open through 90 degrees (its max). putting calipers on a spent bullet will almost never give you the maximum expansion. as long as it fully expands and retains the bulk of its mass (which the HST does very well even though its not bonded) then I'm happy with it.

    love the gel test. nice job.

    You misunderstood my post. That's not what I was asking the OP for.

    Nice test. This reinforces what I had already believed about this load.

    I wasn't responding to your question. Just adding a thought in response to the the data table in the OP.

    I believe the max expansion is actually the max wound/stretch cavity measurement I recently added to the data sheet. You can see the wings off the central wound channel start small and grow until they start getting smaller again. That mimics the expansion behavior of the bullet. I'll know for sure if I run some copper DPX since their petals don't fold back against the bullet shank.

    Thanks for your positive comments about the test.

    It is .6355" for the high and low average.
